dea6ce6eb1 Merge r1065: Don't bail if a thread's stack pointer is invalid 
Currently, if a thread's stack pointer is not within a valid memory page,
the minidump writing will fail with an error.  This change allows an invalid
stack pointer by simply setting the memory size to zero in the minidump.
The processing code already checks for the size being zero, although it
currently just gives an error (see https://breakpad.appspot.com/413002/).

13d9e27ef0 Fix Breakpad unit tests build for Android. 
This patch contains the source-related fixes to ensure that
the Breakpad unit tests build properly when targetting Android.

Calling 'make check' still fails because there is still no
way to run the unit test programs on a device. This will be
addressed by a future patch.

Important notes:

- You must target Android API level 9 (Gingerbread) or higher
  to build the unit tests. This requirement is due to the
  current GTest revision used in the breakpad source tree.

- This patch adds headers providing inlined C library functions
  missing from the NDK (see src/common/android/testing). They
  are inlined to avoid modifying Makefile.am and other build
  files.

- Similarly, the <wchar.h> header-fix under
  src/common/android/testing/include is only required by
  GTest's current revision. E.g. it's not needed when building
  Breakpad as part of Chromium which uses a more up-to-date
  revision.

690e294ece Fix the tools and processor build for Android 
This small patch allows the build of the tools and processor
when targetting Android with the Automake/Autconf build.

Not that these necessarily work correctly at the moment,
but there is no need for --disable-tools --disable-processor
now when using --host=arm-linux-androideabi or
--host=i686-linux-android.

+ Modify android/run-checks.sh to build all binaries with
  the Automake build.

62d486be7c Improve Android support 
This patch remove many Android-specific #ifdefs from the Breakpad
source code. This is achieved by providing "fixed-up" platform
headers (e.g. <signal.h> or <sys/user,h>), in the new directory
src/common/android/include/, which masks differences between
the NDK and GLibc headers.

The old "android_link.h" and "android_ucontext.h" are moved
and renamed.

This also requires putting this directory as the first
include path during Android-hosted builds, hence the
modification of Makefile.am and configure.ac

3f264d250b android: Add --abi option to android/run-checks.sh 
This patch adds an option to android/run-checks.sh to specify
the target ABI. For example, by using the following line:

  android/run-checks.sh --abi=x86 --no-device

One can check the Android/x86 build of Google Breakpad (which
still fails for reasons that will be fixed in later patches).

Another use is to force the 'armeabi' ABI even when an
ARMv7-A device is connected (which uses the 'armeabi-v7a'
by default, but supports 'armeabi' as well).

0bed408b15 Add Android NDK module definition + sample application 
This patch adds a new directory named "android/" which contains
the following:

- A NDK build system module definition for the Google Breakpad
  client library. This can be used by developers using the ndk-build
  build system to more easily build and use the client library in
  their own programs.

- A sample application demonstrating how to use the module,
  as well as test that the library works properly during a
  crash.

- A shell script (run-checks.sh) that will check everything
  for you automatically, including:

  - Rebuilding the host Google Breakpad host package with configure/make
  - Rebuilding the Android client library with configure/make
  - Rebuilding the Android client library and test program with ndk-build
  - Running the crashing test program, extract minidump, dump symbols,
    generate a stack trace and check that it has correct source file
    locations.

For more details, run android/run-checks.sh --help-all

+ Updates to the README.ANDROID documentation.

This gives more information about the system image the device runs on.

a15a2a6811 Allow the minidump writer to collect handle data so that resulting dump contains 
information about opened handles (!handle) and handle operations trace
(!htrace).

Depending on the dump type different amount of data is collected. For a full
dump all handles and complete handle trace are included to the dump. In the case
of a minidump the list of handle operations for a single handle value (the last
handle value that caused STATUS_INVALID_HANDLE exception) is recorded. In either
case the handle trace should be explicitly enabled by the client process (or by
a debugger) in order to produce any handle trace data.

05d61dfd83 Bits necessary to send the reports along with the minidumps. 
Currently the log file and the minidump are uploaded in two consequent requests,
thus they get different report ids and it's hard to associate them to each

This CL makes the crash uploader send the minidump and the log file together in
a single multipart request, so that they have the same report id and are
accessible from the same landing page.

78373e45c5 Fix for putting main module as first one in minidump 
The first module in a minidump is expected to be for the main executable.
We used to assume that /proc/<pid>/maps always showed that one first, but in
some cases that is no longer true (see comment #7 of the bug).  So this
change makes use of the entry point stored in auxv to make sure we put the
correct module first.

I have another change in the works that can sometimes affect the module

Instead of using exc_server, the message is parsed directly, and the minidump
is created, then the app is killed.

 Moreover, the only catch exception is exception_raise. This patch remove all
 rereference to exception_raise_state and exception_raise_state_identity.

907f95c5bd Modify CrashGenerator::CreateChildCrash to copy proc files. 
This patch is taken from the downstream version of breakpad in
Chromium OS:  https://gerrit.chromium.org/gerrit/15148

LinuxCoreDumperTest previously assumes the proc files of the child
process created by CrashGenerator::CreateChildCrash() have the same
content as its parent process, which may not be true. This CL modifies
CrashGenerator to copy the proc files of the child process, created by
CreateChildCrash(), before crashing that process.

5e4f6feaf6 Breakpad DWARF: Add support for DWARF 4 attribute forms. 
This patch allows Breakpad's DWARF reader to at least read or skip
attributes using the new forms defined in version 4 of the DWARF
specification, instead of crashing.

Attributes encoded using DW_FORM_flag_present, DW_FORM_sec_offset, and
DW_FORM_exprloc should work fine now. However, compilation units using
DW_FORM_ref_sig8 to refer to types in .debug_types will need further work
to support. (GCC 4.6.2 does not emit .debug_types sections.)

Specifically:

- dwarf2reader::DwarfForm gets new values.
- dwarf2reader::Dwarf2Handler and dwarf2reader::DIEHandler get new handler
  methods, named ProcessAttributeSignature, for DW_FORM_ref_sig8 attributes.
- dwarf2reader::CompilationUnit reads DW_FORM_ref_sig8 attributes, and
  passes them to ProcessAttributeSignature. It also gets support for
  DW_FORM_sec_offset, DW_FORM_exprloc, and DW_FORM_flag_present, using the
  existing appropriate ProcessAttribute* methods.
- dwarf2reader::DIEDispatcher passes through ProcessAttributeSignature
  attributes to its DIEHandler.
- Unit tests are updated.

403124f9e2 Fix test addresses to use uintptr_t instead of u_int64_t. 
When a variable is used to set (and lookup) MappingInfo's "start_addr"
field, it needs to match types -- which is "uintptr_t".  When Chrome OS
updated the 'make' that's used for building, the 32-bit "char *" had
sign-extended when cast up to a u_int64_t -- maybe because pointers were
unsigned before and then changed to be signed -- and that caused the address
lookup to fail.

5951dd28af Eliminate another source of UnspecifiedStackSignature crash dumps. 
Manufacturing an exception record improves the crash reporting, since then
the crashes get bucketed by the call stack leading to the dump, instead of 
all falling into a misc bucket that nobody ever looks at.
Currently these are occuring through e.g. dumps from the base watchdog.

ae5193c24e Replace readlink calls with a safer version that guarantees NULL-termination. 
This patch is part of a bigger patch that helps merging the breakpad code
with the modified version in Chromium OS.

Specifically, this patch makes the following changes:
1. Add a SafeReadLink function that wraps sys_readlink() to resolve a
   symbolic link but guarantees the result is NULL-terminated on success.
2. Refactor other source code to use SafeReadLink instead of readlink()
   or sys_readlink().

BUG=455
TEST=Tested the following:
1. Build on 32-bit and 64-bit Linux with gcc 4.4.3 and gcc 4.6.
2. Build on Mac OS X 10.6.8 with gcc 4.2 and clang 3.0 (with latest gmock).
3. All unit tests pass.
4. Run minidump-2-core to covnert a minidump file to a core file.

f044345c23 Refactor code in preparation of merging with the fork in Chromium OS. 
This patch is part of a bigger patch that helps merging the breakpad code
with the modified version in Chromium OS.

Specifically, this patch makes the following changes:
1. Add a MemoryRange class for encapsulating and checking read access
   to a contiguous range of memory.
2. Add a MemoryMappedFile class for mapping a file into memory for
   read-only access.
3. Refactor other source code to use MemoryMappedFile.

BUG=455
TEST=Tested the following:
1. Build on 32-bit and 64-bit Linux with gcc 4.4.3 and gcc 4.6.

25b886a7fd Fix ContextDeathTest.X86BadFlags unit test on Mac OS X. 
The assertion (context.context_flags & MD_CONTEXT_X86) in synth_minidump.cc
produces a different message on Mac OS X than other platforms. This patch
changes the ContextDeathTest.X86BadFlags test to handle both message patterns.

BUG=424

 2) Dump are saved when a crash occures but are not automatically send to the
    server.
 3) Breakpad.h contains function to check if a dump must be uploaded, and to
    upload a dump.
 4) The code is copy pasting a log of Breakpad implementation for Mac OS. It
    might be possible to do some refactoring.

29b0d713c9 Fix harmless warning in dwarf_cfi_to_module.cc. 
This function already establishes that (signed) i must be positive by the time
it assigns it to (unsigned) reg. Because reg is unsigned, it is impossible for
it to be negative. Because i was already checked for positivity, this check
can be removed entirely. It was not a miswritten check that intended to check
i instead of reg, because i is already checked.

This addresses the following warning:

a75f1bf9e7 Fix harmless printf abuse in symupload. 
symupload printed -[NSData length], an NSUInteger, using %lu. %lu is proper
to print a "long" as unsigned, but NSUInteger is a typedef for "unsigned int"
when building for 32-bit. This would not have caused any problems, because in
the 32-bit model, both int and long are 32 bits wide. In the 64-bit model,
long is 64 bits wide, but NSUInteger is defiend as "unsigned long", so there
wouldn't have even been a warning in that case.

This addresses the following warning:

symupload.m:137:30:{137:28-137:31}{137:46-137:59}: warning: conversion specifies type 'unsigned long' but the argument has type 'NSUInteger' (aka 'unsigned int') [-Wformat]

During the build of Breakpad itself (especially in Chromium), there is no
Breakpad.framework/Headers in which to locate BreakpadDefines.h, so the
framework-style #include of <Breakpad/BreakpadDefines.h> is not able to find
anything to #include. Using the "BreakpadDefines.h" form should always locate
this file next to Breakpad.h whether it's in the framework or in the source

1e9dbde88a Ensure crash reports will be uploaded on the Mac. 
Regression from Breakpad r842 (Chromium r103778) - browser crash reports were
uploaded, but renderer crash reports were not. Messages such as these may have
been logged:

com.apple.launchd.peruser.x[y] could not lookup DNS configuration info
service: (ipc/send) invalid destination port
com.apple.launchd.peruser.x[y] Breakpad Reporter: Send Error: Error
Domain=NSURLErrorDomain Code=-1009 UserInfo=z "This computer’s Internet
connection appears to be offline." Underlying Error=(Error
Domain=kCFErrorDomainCFNetwork Code=-1009 UserInfo=w "This computer’s Internet
connection appears to be offline.")

When OnDemandServer establishes the bootstrap subset, it will now register the
parent bootstrap port in the subset namespace so that the Inspector can
recover this port and switch to it. The Sender, launched by the Inspector,
relies on the bootstrap port being set properly.

BUG=chromium:99252
TEST=All test cases from Chromium r103778 (bug chromium:28547) plus:
     about:crash should generate a crash report which should be uploaded,
     provided that throttling is not in effect. Remove or edit
     ~/Library/Preferences/com.Breakpad.crash_report_sender.plist to defeat
     throttling. Also verify that about:inducebrowsercrashforrealz works.

e7b75dbcc3 Use a bootstrap subset port for the inspector, tying the subset to the 
lifetime of the task to be monitored, the invoking task. This allows the
bootstrap server (in launchd) to automatically clean up the Mach server
registration when the task being monitored exits, avoiding leaks of
com.Breakpad.Inspector(pid) ports in "launchctl bslist".

BUG=chromium:28547
TEST=Handler should still crash catches, but inspector ports should no longer
     show up in "launchctl bslist". They should show up under a subset port in
     "launchctl bstree" instead. "launchctl bstree" must be invoked as root.

1a1890a52a Adjust MD_CONTEXT_CPU_MASK to reflect reality, fix some code so it can handle dumps using the old value for MD_CONTEXT_ARM 
The value of MD_CONTEXT_CPU_MASK in use assumes that only the lower 6 bits are used for flags, and the upper 26 bits are for the CPU type. However, as of Windows 7 SP1, the 7th bit is being used as a flag (per http://msdn.microsoft.com/en-us/library/hh134238%28v=vs.85%29.aspx and the Windows SDK headers). Adjusting MD_CONTEXT_CPU_MASK works, but unfortunately that masks off the existing value of MD_CONTEXT_ARM. This patch also changes the value of MD_CONTEXT_ARM and adjusts the minidump context reading machinery to gracefully handle minidumps with the old value.

60a883212f Fix CalculateStackSize to behave properly when the main thread's stack is 
split up into multiple regions.

An older workaround relyied on known fixed stack locations and only filled in
the initial page of the stack if it was in a distinct region. The new approach
looks upwards for additional regions that appear to be part of the same stack.

With PIE on Lion, the stack no longer begins at a fixed address, so the older
workaround became ineffective.

e919fdd63b Wean Mac Breakpad off of its OpenSSL libcrypto dependency. 
This libcrypto dependency sucks. Linking against OpenSSL is sort of broken in
certain Mac OS X SDKs. libcrypto was only being used to provide an MD5
implementation. Breakpad already has its own MD5 implementation, so just use
that instead.

To be perfectly honest, on modern systems, nothing should be making MD5
hashes of modules anyway, because everything has an embedded LC_UUID.

The project file changes just remove libcrypto and add md5.c as needed.

A bonus (and untested) fix for on_demand_symbol_supplier.mm is included to
account for changes in r794.

a4a9922512 Issue 417: update unit tests after adding unnamed function detection 
In r779, at the last moment, I added a default call count expectation for
the UnnamedFunction warning to the CUFixtureBase constructor, but didn't
re-run the tests. This patch adjusts all affected tests.

fd18beeb5c Google Breakpad Issue 417: Handle DWARF that omits function names. 
This patch makes sure dump_syms behaves properly when presented with
malformed DWARF data that provides no name for a function. We print a
warning message to stderr, and subsitute "<name omitted>" for the empty
string, so that the "FUNC" record written to the symbol file for the
function is still well-formed. (We may have line number data covering the
function, so it would be a shame to omit the function altogether.)

Unit tests included.

bf25801d83 Put PUBLIC lines in Mac symbol files. 
Exported symbols on Mach-O binaries are defined in a STABS section. This patch makes stabs_reader handle them, adds support for Extern symbols in the Module class (which are output as PUBLIC lines in symbol files), and the proper processing in stabs_to_module to hook it all up.

2b4274afc4 Added libdisasm to the repository. This library is no longer under development so there 
is no reason not to keep it locally. Implemented a basic disassembler which can be used
to scan bytecode for interesting conditions. This should be pretty easy to add to for
things other than exploitability if there is a desire. This also adds several tests to
the windows exploitability ranking code to take advantage of the disassembler for x86
code.

c2c4192c1b Breakpad DWARF Reader: Ignore padding at the end of the compilation unit. 
After the final DIE in a compilation unit, there may be any number of
zero bytes present. This is meant to allow producers to align
compilation unit starting points when necessary.

This patch changes the dwarf2reader::CompilationUnit class to skip
those zero bytes, rather than interpreting them as 'end of children'
markers for DIEs that do not exist. Without this change, the padding
bytes will cause the reader to attempt to pop an offset from an empty
stack, and call EndDIE with a garbage offset.

The 64-bit cleanups made last month (http://breakpad.appspot.com/133001/show)
introduced unit test suite failures when built for a 32-bit architecture. The
fix for those test suite failures (http://breakpad.appspot.com/140001/show)
introduce build failures on Linux.

0ab73db415 Breakpad uses x86 as the architecture name, not i386. Most tools don't care 
what architecture name is shown in a symbol file's MODULE line, but the Mac
crash_report tool's on_demand_symbol_supplier does. The new Mac dumper
inadvertently used i386. Correct that to make it x86. Temporarily make the
on_demand_symbol_supplier accept symbol files whose architecture is i386.
Also add x86_64 to the set of architectures that the on_demand_symbol_supplier
considers valid.

615d2c0d6d Separate the "hello" message from the parameter messages in 
Inspector::ReadMessages as was done before r627. The "hello" message contains
the parameter count and is referenced while the message reader loops through
parameter messages. Prior to r627, both messages were named |message|, which
was confusing, probably caused a compiler warning, and apparently provided the
motivation to share them. This caused the crash inspector to fail to properly
collect the parameters. The common failure mode (although others are possible)
was for the inspector to attempt tor read more parameter messages than were
available, resulting in an IPC timeout and inspector death. No crash report
would be written, and the application expecting its crash to be inspected
would time out waiting for a response from the inspector and then _exit. This
is effectively a failure to properly handle crashes.

The inner message is reintroduced, and named parameter_message for
disambiguation.

This patch avoids allocating many copies of identical strings appearing in
debugging information. Without this patch, running dump_syms on Mozilla's
libxul.so (with 173MiB of debugging information) has a peak resident set of
around 450MiB. With this patch, the peak is around 365MiB.

c5f5e0ae65 Breakpad Linux dumper: Don't map file into memory a second time just to compute file ID 
At present, the Linux symbol dumper maps the ELF file into memory to
examine the debugging information it contains, but then also calls
google_breakpad::FileID::ElfFileIdentifier, which maps the ELF file into
memory again. Some of our object files are large; Mozilla's libxul.so is
1.1GiB. Trying to map such files twice can interfere with tools like
valgrind that map themselves into high addresses (in an attempt to stay out
of the way of ordinary programs).

The FileID class has another method, ElfFileIdentifierFromMappedFile, that
operates on an already-loaded image of the file; use that instead.

6869f2e1b3 Breakpad DWARF CFI parser: Use the proper type for offsets in CallFrameInfo::Rule subclasses. 
The subclasses of CallFrameInfo::Rule store the rule currently in
force for recovering a register or computing the canonical frame
address. Their sole responsibility is to accurately convey rules from
the parser, which creates them, to a CallFrameInfo::Handler member
function, which consumes them. So, the types of their data members
should match those of the corresponding arguments of the corresponding
Handler member function.

CallFrameInfo::OffsetRule and CallFrameInfo::ValOffsetRule use an
'int' to store the rule's offset value, but
CallFrameInfo::Handler::OffsetRule and ...::ValOffsetRule expect a
'long'.  On ABIs where 'long' is larger than 'int', this can cause
values to be truncated or sign-extended unexpectedly.

This patch changes those members to 'long'.

Fortunately, offsets appearing in real DWARF call frame information
never even come close to the limits of a 32-bit int, so this bug is
unlikely to cause any practical problems.

1adc07f0ff Breakpad Mac symbol dumper: Unify with Linux dumper; support DWARF CFI. 
This patch rewrites the Mac symbol dumper to use the same set of classes
the Linux dumper does for reading debugging information from various
sources, consolidating them into a single table, and writing that out as a
Breakpad symbol file.

In the process, it also adds support for dumping DWARF call frame
information and .eh_frame exception-handling information as Breakpad 'STACK
CFI' records. This allows the Breakpad processor to generate stack traces
from code compiled with -fomit-frame-pointer.

The patch also replaces the DumpSymbols Objective C++ class with
google_breakpad::DumpSymbols, a plain C++ class. The code still uses some
Objective C++ to use the Foundation facilities for dealing with file names
in a file-system-independent fashion, and for examining the contents of
.dSYM bundles.

Since the code has been entirely rewritten, I have changed the author
lines.

35c41e00ee Breakpad Mac symbol dumper: Add new Mach-O reader class. 
This patch adds files defining new classes in the google_breakpad::Mach_O
namespace for parsing fat binaries and Mach-O files. These are used in the
new dumper to handle STABS debugging information, DWARF call frame
information, and .eh_frame exception handling stack walking information.

These new classes are independent of endianness and word size, and
therefore can be used on binaries of all the relevant architectures: x86,
x86_64, ppc, and ARM.

The patch adds a complete set of unit tests for the new classes.

8cf0a52bec Moved exception_handler_test to the more aptly named exception_handler_death_test. It doesn't test anything else than death and exit. 
Created the exception_handler_test that test the generation of dump and the dumps themselves.
Moved all dump analysis code from minidump to its right class DumpAnalysis. The class is used by both minidump_test and exception_handler_test. The tests are way simpler that way (ie. no handling of HANDLE).
minidump_test now uses the minidump_generator class instead of using Win32. It works well and pass all tests.
exception_handler now passes both the exception and assertion infos to the client to generate the dump. If one is NULL it's going to be handled correctly.
crash_generation_client can now RequestDump with both exception and assertion info.
minidump_generator returns both the mini and full dump string pointers, and output both (or either) depending on which was generated.
All original interfaces and method signature are still there, but call the new functions if possible.

297b1e5a06 Copied minidump_test.cc from chrome_frame (see http://src.chromium.org/viewvc/chrome/trunk/src/chrome_frame/crash_reporting/minidump_test.cc). 
I had to remove the dependency from base (was using FilePath and ScopedHandle, replaced them by standard std::wstring and HANDLE). Also removed the logging and the main from the original files.

This will serve as a base for testing breakpad's dump generation. It is kept like this for easier tracking.

073a7f6695 Breakpad unit tests: Add support for clipped-size null-terminated strings 
to TestAssembler::Section.

This patch helps the TestAssembler classes generate Mach-O object files for

This patch adds a new AppendCString overloading to TestAssembler::Section
for emitting null-terminated strings in fixed-length buffers, where the
string is truncated and the terminating null character omitted if the
string is too large for the buffer.

The patch includes unit tests for the new AppendCString overloading. It
also provides some for the existing overloading, which had been neglected.

25b512d64d Breakpad symbol dumper: Promise that Module::SetLoadAddress can be called at any time. 
It's possible to imagine an implementation of google_breakpad::Module in
which calling SetLoadAddress at different times as the Module is populated
would produce different output. For the Mac dumper, we'd like to depend on
its current behavior --- that the load address is subtracted off only when
writing the symbol file, and can be set at any time prior to that.

This patch makes that promise part of Module's contract, and adjusts the
test suite to verify that that promise is met.

775c6f7640 Breakpad Linux dumper: Handle STABS-in-symbol-table, and line number records outside functions. 
This patch addresses two differences between Linux and Macintosh OS X STABS
data:

- StabsReader assumes that the STABS entries follow the conventions for
  storing STABS data in object file sections (that is, .stabs and
  .stabstr), rather than in the object files's linker symbol table. On Mac
  OS X, STABS entries live in the Mach-O file's LC_SYMTAB load command,
  along with all the other linker symbols; they are not grouped into units
  by N_UNDF entries.

  This patch adds a boolean argument to the StabsReader constructor
  indicating whether the parser should treat N_UNDF entries as unit
  boundaries; this argument should be true on Linux, and false on Mac. The
  patch changes src/common/linux/dump_symbols.cc to pass this new argument.

- Mac OS X STABS place SLINE (line number) records immediately before the
  FUN record for the function to which they belong, and the values of such
  records are absolute, not relative to the function start.

  This patch extends the parser to queue up such records and report them to
  the handler when we do see the FUN record. The meaning of
  StabsHandler::Line remains unchanged; existing handlers do not need to be
  adjusted.

This patch also adds unit tests for the new parser behaviors.

b0ec96cee2 Breakpad Linux dumper: Make StabsReader independent of endianness and word size. 
StabsReader simply applies a reinterpret_cast to treat the stab entry data
as an array of 'struct nlist' structures, making the parser specific on the
host endianness, word size, and alignment rules. On Mac OS X, a single fat
binary file may contain object files of different ABIs, of which the user
chooses one at run time.

This patch changes the parser to read the data using the google_breakpad::
ByteCursor class, which can handle different endiannesses and word sizes.
The StabsReader constructor now takes arguments indicating the endianness
of the data and the size of each entry's value field. The patch changes
src/common/linux/dump_symbols.cc to pass the new argument.

This patch changes the StabsReader unit tests to use the google_breakpad::
TestAssembler classes to generate test data, rather than reading it from a
file. This makes it easy to generate test data in various endiannesses and
word sizes. It also adds tests for the new parser behaviors.

56e7a3c65d Breakpad Linux Dumper: Have DumpStabsHandler free accumulated functions if Finalize is not called 
The DumpStabsHandler class creates Module::Function objects as it processes
data from the StabsReader, but waits to add the Functions to the Module
until all parsing is complete and its Finalize member function is called,
so that it can compute line and function end addresses that the STABS data
may have left implicit.

If the DumpStabsHandler is destructed before its Finalize method is called,
it fails to free the Functions it has created, but not yet added to the
Module. (Adding a Function to a Module transfers ownership of the Function
to the Module.)

This adds a destructor to DumpStabsHandler which takes care of freeing any
Functions that it still owns.

504280af60 Breakpad Dumper: Move CFI register names to DwarfCFIToModule class. 
At the moment, the mappings from register numbers appearing in DWARF CFI
and .eh_frame exception handling sections to the appropriate
processor-specific names are in src/common/linux/dump_syms.cc. However, the
numberings are (for the most part) the same on all platforms using DWARF,
so there's no reason those tables shouldn't be shared between the Linux and
Mac symbol dumpers.

This patch moves the tables into a nested class of DwarfCFIToModule, so
they the Mac dumper can use them when it is changed to use
DwarfCFIToModule.

608d142aaa Breakpad DWARF parser: correct comments regarding dynamic_cast. 
The comments don't accurately describe what the style guide says.

Regardless of what the style guide says, RTTI seems to make trouble in
practice, because so many people build with it disabled. Since only the
symbol dumper uses RTTI, not the client library, it may be practical for
people to simply enable RTTI for the dumper. Failing that, it may be best
in the long run to violate the style guide and make the code work sans
RTTI.

c609f474a9 Breakpad: Support DWARF CFI-driven stack walking on ARM. 
This patch allows the Breakpad minidump processor to use data from
STACK CFI records to generate stack traces for the ARM processor.

In the symbol dumper, we need a table mapping DWARF CFI register
numbers to their names: STACK CFI records refer to registers by name.

In the processor, we expand StackwalkerARM::GetCallerFrame to see if
there are STACK CFI records covering the callee, and then use those to
recover the caller's register values.

There's no good reason the ARM walker couldn't use the SimpleCFIWalker
interface declared in cfi_frame_info.h. Unfortunately, that interface
assumes that one can map register names to member pointers of the raw
context type, while MDRawContextARM uses an array to hold the
registers' values: C++ pointer-to-member types can't refer to elements
of member arrays. So we have to write out SimpleCFIWalker::FindCallerRegisters
in StackwalkerARM::GetCallerFrame.

We define enum MDARMRegisterNumbers in minidump_cpu_arm.h, for
convenience in referring to certain ARM registers with dedicated
purposes, like the stack pointer and the PC.

We define validity flags in StackFrameARM for all the registers, since
CFI could theoretically recover any of them. In the same vein, we
expand minidump_stackwalk.cc to print the values of all valid
callee-saves registers in the context --- and use the proper names for
special-purpose registers.

We provide unit tests that give full code and branch coverage (with
minor exceptions). We add a testing interface to StackwalkerARM that
allows us to create context frames that lack some register values.

Extend dump_syms to look for a .eh_frame section, and if it is

There's no need for DwarfCFIToModule to check the version numbers; if
CallFrameInfo can parse it, DwarfCFIToModule should be able to handle
it. Adjust tests accordingly.

841ad48a37 Breakpad Linux symbol dumper: Handle programs linked with --gc-sections. 
As explained in the code:

Given the right options, the GNU toolchain will omit unreferenced
functions from the final executable. Unfortunately, when it does so,
it does not remove the associated portions of the line number program;
instead, it lets the symbol references in the DW_LNE_set_address
instructions pointing to the now-deleted code resolve to zero. Given
this input, the DWARF line parser will call AddLine with a series of
lines starting at address zero.

Rather than collecting series of lines describing code that is not
there, we should drop them. Since the linker doesn't explicitly
distinguish references to dropped sections from genuine references to
zero, we must use a heuristic. We have chosen:

Some versions of the libstdc++, the GNU standard C++ library, have
stream extractors for unsigned integer values that permit a leading
'-' sign (6.0.13); others do not (6.0.9). Regardless of the behavior
of the extractors, Breakpad postfix expressions should support

d6fb5a7c51 Breakpad Linux dumper: Record AbstractOrigin entries for all DIEs that need them. 
Any DIE with an DW_AT_inline attribute can be cited by
DW_AT_abstract_origin attributes --- even if the value of the
DW_AT_inline attribute is DW_INL_not_inlined. Thus, we need to set the
inline_ flag on all such DIEs, regardless of the attribute's value.
This allows us to find names in situations like this:

6de1b75da4 Breakpad Linux dumper: Compare section names correctly. 
FindSectionByName will return the first section whose name starts with
NAME, because strncmp stops the comparison once NAME's characters have
been found to match. The comparison stops before the terminating '\0'.
For example, if we search for the section named ".eh_frame", we may
get the section named ".eh_frame_hdr".

Instead, check that the section name section has enough space to store
the complete name with its terminating '\0', and then use strcmp,
which will never examine more than strlen(NAME) + 1 bytes from the
section name section, regardless of its contents, and will require the
terminating '\0' to match as well.

The Google C++ Style Guide requires each file to have an author notice

don't think putting an author notice on the files is a good idea; it's
odd to have the original author retain prominence even if the file has
been heavily edited by others; the version control system answers this
question more accurately. This is only for Style Guide compliance. The
Apache group decided to discourage author annotations, partially for
these reasons:

03ebc1d245 Breakpad processor: Fix function and public symbol lookup. 
In r480, I botched the change to make the comparisons that decide
whether an address falls within a function's range safe from overflow.
The original code said:

  address >= function_base && address < function_base + function_size

which is fine unless the function abuts the end of the address space,
in which case the addition overflows and you get a false negative.

My change subtracted function_size from both sides of the latter
comparison, which is meaning-preserving in true math, and gets you:

  address >= function_base && address - function_size < function_base

This not only reads strangely, but also still overflows if
function_size is greater than address. That's rare, but I've added a
case to the unit tests that checks it.

My intent had been to replace the addition which could overflow with a
subtraction that was known not to overflow, namely:

  address >= function_base && address - function_base < function_size

This is equivalent to the original in true math, and because of the
first comparison, we know the subtraction won't underflow in MemAddr
math.

The patch includes similar fixes to the public symbol lookup code, and
to FindWindowsFrameInfo, which was the only other function affected by
r480.

057aa1f617 Breakpad Linux Dumper: Add DWARF support. 
This adds DWARF support to the Breakpad Linux dumper. This is
implemented as two handler classes: google_breakpad::DwarfCUToModule
accepts data from dwarf2reader::CompilationUnit, and
google_breakpad::DwarfLineToModule accepts data from a
dwarf2reader::LineInfo, each populating a google_breakpad::Module with
the results. Behaviors specific to particular source languages are
handled by instances of a new class, google_breakpad::Language.

An input executable may contain both STABS and DWARF debugging
information: the dumper automatically recognizes what sorts of
information are available, and integrates the data into a single
output file.

All classes have unit tests, providing line and branch coverage of all
interesting code. Unit tests are written using the Google C++ Testing
Framework, and the Google C++ Mocking Framework where appropriate.

At the moment, the StackWalker GetCallerFrame member function expects
a vector of WindowsFrameInfo structures, even though WindowsFrameInfo
is only used or useful on one one implementation (StackWalkerX86).

This patch changes StackWalker::GetCallerFrame to no longer expect the
WindowsFrameInfo structures, and changes all implementations to match.

In particular, StackWalkerX86 is changed to find the WindowsFrameInfo
data itself, and store a pointer to whatever it got in the StackFrame
object itself (which is really a StackFrameX86).

To allow GetCallerFrame implementations to look up stack walking data,
StackWalker::resolver_ needs to be made protected, not private.

5251e64f48 Breakpad Linux dumper: STABS reader incorrectly assumes a single compilation unit 
The stabs reading code in google-breakpad incorrectly assumes that the
stabs data is a single compilation unit. Specifically, it ignores
N_UNDF stabs and assumes that all string indices are relative to the
beginning of the .stabstr section.

This is true when linking with the GNU linker by default, because the
GNU linker optimizes stabs debug info. The gold linker does not do
this optimization. It can be disabled when using the GNU linker with
the --traditional-format command line option.

For more details of the problem, see:

http://sourceware.org/bugzilla/show_bug.cgi?id=10338
http://code.google.com/p/google-breakpad/issues/detail?id=359

This patch adds unit tests that reproduce the failure, and fixes the
stabs parser.

e9faf54828 Issue 49013: Breakpad Processor: Use a separate API to retrieve Windows stack debugging info. 
At the moment, FillSourceLineInfo returns Windows DIA-based stack
walking data. In addition to being ugly, this makes it difficult to
provide access to DWARF CFI-based stack walking data in a symmetrical
way.

This patch changes FillSourceLineInfo to do the single job its name
suggests, and adds a second member function to
SourceLineResolverInterface to retrieve Windows DIA stack walking
information. A sibling member function will provide access to DWARF
CFI stack walking data.

7a77f45f79 Breakpad DWARF parser: Fix up documentation for DWARF reader classes. 
Fix typos.

For CompilationUnit::Start, I was confused by the '-' in the original
comment, taking it for a parenthetic clause marker, assuming an
implicit "of the next compilation unit" at the end of the sentence.

The comments should refer to the ".debug_info" section, not the
"debug_info" section. The latter is not the section name actually used
on any system (ELF or Mach-O), and the former is the name prescribed
by the DWARF spec.

Some of the comments for ProcessAttribute* member functions claim that
OFFSET is from the start of the compilation unit, but that's not so:
the code has always passed an offset relative to the start of the
.debug_info section.

src/common/dwarf/dwarf2reader.cc uses the old-fashioned <stdio.h>
facilities to report errors. Ideally, we would add a 'Warning' message
to the handler and make the client responsible for dealing with the
errors, but this at least allows us to compile.

Ubuntu 9.10 uses GCC 4.4.1; under older versions of GCC, this wasn't a
problem, probably because stdio.h was being brought in inadvertently
somewhere else.

bdd7ca54cd Issue 42002: Breakpad DWARF parser: avoid using <stdint.h> type 
It seems that a use of the <stdint.h> type uintptr_t has crept into
the DWARF parser. This defines a workaround for the GNU compilers
(tested on both Mac and Linux) which will raise an error if it doesn't
work.

My personal preference would be just to assume that the <stdint.h>
header is available and use the standard types everywhere, but 1) that
would be a large change, likely to make merges with the other branches
of the DWARF parser more difficult, and 2) it would make it quite
difficult to build under Microsoft Visual Studio, which doesn't have
the <stdint.h> header; Microsoft has said they have no plans to
provide it, as they would rather "focus their efforts" on C++ and
.NET.

7f941f990a Linux dumper: Add unit tests for google_breakpad::StabsReader. 
The test system is based on Google C++ Testing Framework and the
Google C++ Mocking Framework.

This includes a parser that turns human-readable input files ("mock
stabs") into .stab and .stabstr section contents, which we can then
pass to a StabsReader instance, using a handler object written with
GoogleMock. The 'make check' target in src/tools/linux/dump_syms runs
this.

The supplied input file is pretty small, but I've done coverage
testing, and it does cover the parser.

I thought the mock stabs parser would be less elaborate than it turned
out to be. Lesson learned.

c426b3d98a Breakpad: Don't use the deprecated __gnu_cxx::hash_map container. 
Modern GNU compilers warn about the #inclusion of <ext/hash_map>; that
container is deprecated, and code should use <tr1/unordered_map>
instead.  However, to stay within the boundaries of C++ '98, it's
probably fine just to use plain old std::map.

Breakpad uses hash_map in three cases:

o The DWARF reader's SectionMap type maps object file section names to
  data.  This map is consulted once per section kind per DWARF
  compilation unit; it is not performance-critical.

o The Mac dump_syms tool uses it to map machine architectures to
  section maps in Universal binaries.  It's hard to imagine there
  ever being more than two entries in such a map.

o The processor's BasicSourceLineResolver uses a hash_map to map file
  numbers to file names.  This is the map that will probably have the
  most entries, but it's only accessed once per frame, after we've
  found the frame's line entry.

eab03fdb72 Linux dumper: Move the data structures representing the breakpad data into their own class. 
src/linux/common/module.h defines a new class, google_breakpad::Module,
that can represent the contents of a breakpad symbol file.  Module::Write
writes a well-formed symbol file to the given stream.

src/linux/common/dump_symbols.cc can now lose its symbol-file-writing
code, and change DumpStabsHandler to populate a Module object, rather
than the old SymbolInfo/SourceFileInfo/... collection of types.

The code to compute function and line sizes, even in the absence of
reliable size data in STABS, is moved into a new Finalize method of
DumpStabsHandler, which is responsible for completing the Module's
contents.

54bc5cfa2d Linux dumper: Move STABS parsing into its own class. 
With this patch, dump_symbols.cc no longer knows about the details of
the STABS debugging format; that is handled by the StabsReader class.
dump_symbols.cc provides a subclass of StabsHandler that builds
dump_symbols' own representation of the data.

Google Breakpad for Android
===========================
This document explains how to use the Google Breakpad client library
on Android, and later generate valid stack traces from the minidumps
it generates.
Note that this release only supports ARM-based Android systems.
We're working on adding support for x86 and MIPS, but that might
require an udpated NDK release.
I. Building the client library:
===============================
The Android client is built as a static library that you can
link into your own Android native code. There are two ways to
build it:
I.1. Building with ndk-build:
-----------------------------
If you're using the ndk-build build system, you can follow
these simple steps:
1/ Include android/google_breakpad/Android.mk from your own
project's Android.mk
This can be done either directly, or using ndk-build's
import-module feature.
2/ Link the library to one of your modules by using:
LOCAL_STATIC_LIBRARIES += breakpad_client
NOTE: The client library requires a C++ STL implementation,
which you can select with APP_STL in your Application.mk
It has been tested succesfully with both STLport and GNU libstdc++
II.1. Building with a standalone Android toolchain:
---------------------------------------------------
All you need to do is configure your build with the right 'host'
value, and disable the processor and tools, as in:
$GOOGLE_BREAKPAD_PATH/configure --host=arm-linux-androideabi \
--disable-processor \
--disable-tools
make -j4
The library will be under src/client/linux/libbreakpad_client.a
II. Using the client library in Android:
========================================
The usage instructions are very similar to the Linux ones that are
found at http://code.google.com/p/google-breakpad/wiki/LinuxStarterGuide
1/ You need to include "client/linux/handler/exception_handler.h" from a C++
source file.
2/ If you're not using ndk-build, you also need to:
- add $GOOGLE_BREAKPAD_PATH to your compiler include path
- add -llog to your linker flags
Note that ndk-build does that for your automatically.
3/ Keep in mind that there is no /tmp directory on Android.
If you use the library from a regular Android applications, specify a
path under your app-specific storage directory. An alternative is to
store them on the SDCard, but this requires a specific permission.
For a concrete example, see the sample test application under
android/sample_app. See its README for more information.
III. Getting a stack trace on the host:
=======================================
This process is similar to other platforms, but here's a quick example:
1/ Retrieve the minidumps on your development machine.
2/ Dump the symbols for your native libraries with the 'dump_syms' tool.
This first requires building the host version of Google Breakpad, then
calling:
dump_syms $PROJECT_PATH/obj/local/$ABI/libfoo.so > libfoo.so.sym
3/ Create the symbol directory hierarchy.
The first line of the generated libfoo.so.sym will have a "MODULE"
entry that carries a hexadecimal version number, e.g.:
MODULE Linux arm D51B4A5504974FA6ECC1869CAEE3603B0 test_google_breakpad
Note: The second field could be either 'Linux' or 'Android'.
Extract the version number, and a 'symbol' directory, for example:
$PROJECT_PATH/symbols/libfoo.so/$VERSION/
Copy/Move your libfoo.sym file there.
4/ Invoke minidump_stackwalk to create the stack trace:
minidump_stackwalk $MINIDUMP_FILE $PROJECT_PATH/symbols
Note that various helper scripts can be found on the web to automate these
steps.
IV. Verifying the Android build library:
========================================
If you modify Google Breakpad and want to check that it still works correctly
on Android, please run the android/run-test-program.sh script which will do all
necessary verifications for you. This includes:
- Rebuilding the full host package
- Rebuilding the client library with configure/make
- Rebuilding the client library with ndk-build
- Building, installing and running a test crasher program on a device
- Extracting the corresponding minidump, dumping the test program symbols
and generating a stack trace.
- Checking the stack trace for valid source locations.
For more details, please run:
android/run-test-program.sh --help-all

Usage: $PROGNAME [options]
This script is used to check that your Google Breakpad source tree can
be properly built for Android, and that the client library and host tools
work properly together.
"
if [ "$HELP_ALL" ]; then
echo "\
In more details, this script will:
- Rebuild the host version of Google Breakpad in a temporary
directory (with the Auto-tools based build system).
- Rebuild the Android client library with the Google Breakpad build
system (using autotools/configure). This requires that you define
ANDROID_NDK_ROOT in your environment to point to a valid Android NDK
installation directory, or use the --ndk-dir=<path> option.
- Rebuild the Android client library and a test crashing program with the
Android NDK build system (ndk-build).
- Require an Android device connected to your machine, and the 'adb'
tool in your path. They are used to:
- Install and run a test crashing program.
- Extract the corresponding minidump from the device.
- Dump the symbols from the test program on the host with 'dump_syms'
- Generate a stack trace with 'minidump_stackwalk'
- Check the stack trace content for valid source file locations.
You can however skip this requirement and only test the builds by using
the --no-device flag.
By default, all generated files will be created in a temporary directory
that is removed when the script completion. If you want to inspect the
files, use the --no-cleanup option.
Finally, use --verbose to increase the verbosity level, this will help
you see which exact commands are being issues and their result. Use the
flag twice for even more output. Use --quiet to decrease verbosity
instead and run the script silently.
If you have a device connected, the script will probe it to determine
its primary CPU ABI, and build the test program for it. You can however
use the --abi=<name> option to override this (this can be useful to check
the secondary ABI, e.g. using --abi=armeabi to check that such a program
works correctly on an ARMv7-A device).
If you don't have a device connected, the test program will be built (but
not run) with the default '$DEFAULT_ABI' ABI. Again, you can use
--abi=<name> to override this. Valid ABI names are:
$VALID_ABIS

This is a sample Android executable that can be used to test the
Google Breakpad client library on Android.
Its purpose is simply to crash and generate a minidump under /data/local/tmp.
Build instructions:
cd android/sample_app
$NDK/ndk-build
Where $NDK points to a valid Android NDK installation.
Usage instructions:
After buildind the test program, send it to a device, then run it as
the shell UID:
adb push libs/armeabi/test_google_breakpad /data/local/tmp
adb shell /data/local/tmp/test_google_breakpad
This will simply crash after dumping the name of the generated minidump
file.
See jni/test_breakpad.cpp for details.
Use 'armeabi-v7a' instead of 'armeabi' above to test the ARMv7-A version
of the binary.
Note:
If you plan to use the library in a regular Android application, store
the minidump files either to your app-specific directory, or to the SDCard
(the latter requiring a specific permission).

# SYNOPSIS
#
# AX_PTHREAD([ACTION-IF-FOUND[, ACTION-IF-NOT-FOUND]])
#
# DESCRIPTION
#
# This macro figures out how to build C programs using POSIX threads. It
# sets the PTHREAD_LIBS output variable to the threads library and linker
# flags, and the PTHREAD_CFLAGS output variable to any special C compiler
# flags that are needed. (The user can also force certain compiler
# flags/libs to be tested by setting these environment variables.)
#
# Also sets PTHREAD_CC to any special C compiler that is needed for
# multi-threaded programs (defaults to the value of CC otherwise). (This
# is necessary on AIX to use the special cc_r compiler alias.)
#
# NOTE: You are assumed to not only compile your program with these flags,
# but also link it with them as well. e.g. you should link with
# $PTHREAD_CC $CFLAGS $PTHREAD_CFLAGS $LDFLAGS ... $PTHREAD_LIBS $LIBS
#
# If you are only building threads programs, you may wish to use these
# variables in your default LIBS, CFLAGS, and CC:
#
# LIBS="$PTHREAD_LIBS $LIBS"
# CFLAGS="$CFLAGS $PTHREAD_CFLAGS"
# CC="$PTHREAD_CC"
#
# In addition, if the PTHREAD_CREATE_JOINABLE thread-attribute constant
# has a nonstandard name, defines PTHREAD_CREATE_JOINABLE to that name
# (e.g. PTHREAD_CREATE_UNDETACHED on AIX).
#
# ACTION-IF-FOUND is a list of shell commands to run if a threads library
# is found, and ACTION-IF-NOT-FOUND is a list of commands to run it if it
# is not found. If ACTION-IF-FOUND is not specified, the default action
# will define HAVE_PTHREAD.
#
# Please let the authors know if this macro fails on any platform, or if
# you have any other suggestions or comments. This macro was based on work
# by SGJ on autoconf scripts for FFTW (http://www.fftw.org/) (with help
# from M. Frigo), as well as ac_pthread and hb_pthread macros posted by
# Alejandro Forero Cuervo to the autoconf macro repository. We are also
# grateful for the helpful feedback of numerous users.

# -Kthread: Sequent (threads in libc, but -Kthread needed for pthread.h)
# -kthread: FreeBSD kernel threads (preferred to -pthread since SMP-able)
# lthread: LinuxThreads port on FreeBSD (also preferred to -pthread)
# -pthread: Linux/gcc (kernel threads), BSD/gcc (userland threads)
# -pthreads: Solaris/gcc
# -mthreads: Mingw32/gcc, Lynx/gcc
# -mt: Sun Workshop C (may only link SunOS threads [-lthread], but it
# doesn't hurt to check since this sometimes defines pthreads too;
# also defines -D_REENTRANT)

# serial 4 lt~obsolete.m4
# These exist entirely to fool aclocal when bootstrapping libtool.
#
# In the past libtool.m4 has provided macros via AC_DEFUN (or AU_DEFUN)
# which have later been changed to m4_define as they aren't part of the
# exported API, or moved to Autoconf or Automake where they belong.
#
# The trouble is, aclocal is a bit thick. It'll see the old AC_DEFUN
# in /usr/share/aclocal/libtool.m4 and remember it, then when it sees us
# using a macro with the same name in our local m4/libtool.m4 it'll
# pull the old libtool.m4 in (it doesn't see our shiny new m4_define
# and doesn't know about Autoconf macros at all.)
#
# So we provide this file, which has a silly filename so it's always
# included after everything else. This provides aclocal with the
# AC_DEFUNs it wants, but when m4 processes it, it doesn't do anything
# because those macros already exist, or will be overwritten later.
# We use AC_DEFUN over AU_DEFUN for compatibility with aclocal-1.6.
#
# Anytime we withdraw an AC_DEFUN or AU_DEFUN, remember to add it here.
# Yes, that means every name once taken will need to remain here until
# we give up compatibility with versions before 1.7, at which point
# we need to keep only those names which we still refer to.
# This is to help aclocal find these macros, as it can't see m4_define.

// pops up UI for the user. Falls back first to
// CFBundleDisplayName and then to
// BREAKPAD_PRODUCT if not specified.
//
// BREAKPAD_VERSION Product version (e.g., 1.2.3), used

//
// BREAKPAD_VENDOR Vendor name, used in UI (e.g. "A report has
// been created that you can send to <vendor>")
//
// BREAKPAD_URL URL destination for reporting
// REQUIRED
//
// BREAKPAD_DUMP_DIRECTORY The directory to store crash-dumps
// in. By default, we use
// ~/Library/Cache/Breakpad/<BREAKPAD_PRODUCT>
// The path you specify here is tilde-expanded.
//
// BREAKPAD_SERVER_TYPE A parameter that tells Breakpad how to
// rewrite the upload parameters for a specific
// server type. The currently valid values are
// 'socorro' or 'google'. If you want to add

//
// BREAKPAD_SERVER_PARAMETER_DICT A plist dictionary of static
// parameters that are uploaded to the

// content isn't added to the minidump
// but pass as URL parameters when

// configuration parameters and
// parameters meant to be uploaded
// to the server. This string is
// used internally by Breakpad to
// prefix user-supplied parameter
// names so those can be sent to the
// server without leaking Breakpad's
// internal values.
// Returns a new BreakpadRef object on success, NULL otherwise.

// the string is converted to UTF8 before truncation, so any multibyte

// The ExceptionHandler object installs signal handlers for a number of
// signals. We rely on the signal handler running on the thread which crashed
// in order to identify it. This is true of the synchronous signals (SEGV etc),
// but not true of ABRT. Thus, if you send ABRT to yourself in a program which
// uses ExceptionHandler, you need to use tgkill to direct it to the current
// thread.
//
// The signal flow looks like this:
//
// SignalHandler (uses a global stack of ExceptionHandler objects to find
// | one to handle the signal. If the first rejects it, try
// | the second etc...)
// V
// HandleSignal ----------------------------| (clones a new process which
// | | shares an address space with
// (wait for cloned | the crashed process. This
// process) | allows us to ptrace the crashed
// | | process)
// V V
// (set signal handler to ThreadEntry (static function to bounce
// SIG_DFL and rethrow, | back into the object)
// killing the crashed |
// process) V
